Below are links to the raw archives of mailings posted to the CRUST-L email list. The archives are in text-delimited format. They are relatively large, over 1.3 Mb in size, so they may take some time to load.
The files are organized sequentially by month and year. Embedded within each month are from one to eight indexes, each with its own list of subject headings followed by the postings for that period.. Be sure to use specific search terms to speed your searches.
If you find this archive useful, or have a means to improve its utility, let me know.
